FLEXIBLE Application filed Iiecem'oer 20, 1919. Serial No.

T all via/tom it may concern:

e it known that I, LOUIS citizen of the United States, residing at Chicago, in the county of Cool: and state of lllinois, have invented certain new and useful Improvements in Flexible Uperating or Tripping Mechanism, of which the tollowing is a specification.

This invention relates to improvementsin flexible operating or tripping mechanism commonly known as Eowden wire, particularly adapted though not necessarily limited in its use under conditions where it is desired to set in motion, operate or trip an element or part from a remote point and particularly where tie space in which the tripping mechanism is small or'limited and under conditions where the tripping mechanism is not always maintained in a straightline.

A further object is to provide an improved device of this character whichwill be extremely light, compact and durable in construction and embodyinga flexible,

inextensible or incompressible and nonanetallic element within and substantially fil ing the outer casing; so that the axes of the said outer and inner elements will always coincide in any position to which the elements may be bent.

To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substantially the construction, combination and arrange ment of the several parts hereinafter more fully described and claimed and shown in the accompanying; drawing illustrating this invention, and in which;

Figure 1 is a view partly in elevation and partly in section of an improved device of this character constructed in accordance with the principles of this invention,

Fig. 2 is an' elevation showing the parts twisted.

Rcterring more particularly to the drawingthe numeral 10 designates generally a hollow flexible inextcnsible and incompressible outer casing which is constructed of any suitable material and of any desired size and configuration but preferably embodies a flexible housing 11 preferably covered With suitable fabric 12 or if desired the fabric may be omitted. At one end of the housing there is provided an element 13 by Specification of Letters Patent.

means of which the end of the housing may be connected withany fixed support and at the other end oi the housing there is provided another element l t by means of which the end oi' the housing may be grasped and held.

formed is a flexible inextensible and incompressible iio rmetallic element 15 which is constructed ofany suitable material'such as cat-gut or otheranimal fiber, or vegetable fiber such as cord, rope or the like. This elementl is of a diameter to substantially fill the housing and connectedjto one end. 01 the element is an element 16 which is adapted to reciprocate within the element 13 and the extremity 17 of the element 16 is adapted to be connected with fthepart which is to be set into motion, operated or tripped, and the portion 17 of th'eielement 16 preferably projects beyond the end of the element 13. a

r -t the other end of the element 15 and adjacent the element la so as to reciprocate therein is another eleniehtflS which "ore'f erably projects beyond the A; and may be provided with portion it) which is adapted to be grasped by theh: it, so that the operator in operating device will hold the element let in one hand and the ele out 19 in the other hand. in this position and by impartine relative longitudinal shitting:

n'iovement or the elements t at it will he manifest that there will he a similar relative longitudinal movement imparted o the elements 10-15. Inasmuch as the element 15 substantially fills the casing or element 10, it will be manifest that thee-lenient 15 cannot become klllliQCl or distorted in any manner that would prevent it from sliding freely within the casing 10. Inasmuch as the element 15 and the casing 10 are both of a flexible nature these elements maybe tier-Led VVithin the housing thus itatented Nov. 9, 1920. i

or twisted in any manner without impairing;

the free longitudinal shitting movements of the two elements with respect to each. other. If desired there may be provided spring 20 withinthe element 1.4 which tends normally to return the parts to their normal position.

W th this improved construction it will be manifest that by reasonof the fat that the el ment 15 is bound thr u'rh ut substantially its entire ene'th by the clos ly fitting cas no '10, the element will not kink or be distorted with respect to the casing and netting the latter withthe part to be set thereby the longitudinal shifting movement will not be affected.

\Vhile the preferred form of the invention has been herein shown and described, it is to be understood that various changes may be made 1n the details ofeonstruction and n1 thecombination and arrangement of the se eral parts Within the scope of the claims Without departing from the spirit of this in vention.

-What is'claimed as new is 1. A tripping-or operating mechanism of the character described embodying a transversely flexible inextensible' and incompressible casing, a transversely flexible inexte'ngut element Within and"substantially filling the casing, means respectively at one end oi one ofthe parts for anchoring it zind'at the adjacent endoi the other part for connecting the latter With the part to be in motion ortripped, and means respectively at the other ends of the elements whereby ble and incompressible non-metallic ele a relative longitudinal movement of the elements may be produced.

3. A tripping or operating mechanism of the character described embodying a trans- 4- versely flexible inextensible and incompressible casing, a flexible incompressible fibrous element Within and substantially filling said casing, means respectively at one of the ends of one of the parts for anchoring it, and at 4 the adjacent end of the other part for connecting it with the part to be set in motion or tripped, and means respectively at the other ends of the parts whereby a relative longitudinal movement of the elements Illziy be produced. i

e. A tripping or operating mecha the chareeter described embodying aversely flexible ineiztensible and incompressible casing, a transversely flexible inei'lte within and substantially filling ti means respectively at one end. o" elementsi or anchoring it and at 1 cent end oi the other element fer the latter With the part to be or tripped, means respectiv'iy at t e ends of the elements whereby a relati qe it i gitudinal movement of the elements maybe produced. and a spring elem nt interposed 6 between the said casing and the first recited element for returning the parts to their nor-- mal relative positions.

in testimony whereof l. have signed my name to this specification. on this 29th day 7 of Novemben'rt. D.- 1919.v
